or 104 are matched with the second extensions 530 of the enhancing device
500 along the vertical direction Y, the second mounting hole 532 of the
second extension 530 will align with the mounting holes 1017 of the first
extensions 1012, 1022, 1032 or 1042 of the first, second, third or fourth
fixtures 101, 102, 103 or 104. When the second extensions 1013, 1023,
1033 or 1043 of the first, second, third or fourth fixtures 101, 102, 103
or 104 are matched with the first extensions 520 of the enhancing device
500 along the vertical direction Y, the first mounting hole 521 of the
first extension 520 will align with the mounting holes 1018 of the first
extensions 1013, 1023, 1033 or 1043 of the first, second, third or fourth
fixtures 101, 102, 103 or 104. Then, with the application of a bolt and
nut arrangement (not shown in Figures), the fixation of the first,
second, third or fourth fixtures 101, 102, 103 or 104 along the vertical
direction Y with respect to the enhancing device 500 can be readily done.
Of course, in other preferred embodiment, other suitable fixation can be
also implemented to secure the first, second, third or fourth fixtures
101, 102, 103 or 104 and the enhancing device 500, such as interference
fit. As a result, no detailed description is given.

[0081] The reinforced bars 540 span and are bridged between the enhancing
devices 500 of the pair of side beams 300. By this arrangement, the
stability of the cartridge of the glass substrate along the first
horizontal directions X, Y, and the second direction Z can be readily
secured. Of course, as shown in FIG. 19, a plurality of reinforced bars
540 can be arranged along the first direction X so as to enhance the
stability of the cartridge of the glass substrate.

[0082] Referring to FIGS. 21 to 23, the first free locking device 610 is
detachably secured to the first, second, third and fourth fixtures 101,
102, 103, and 104 located on the same side of the side beam 300. As such,
the first, second, third and fourth fixtures 101, 102, 103, and 104 can
be moved as a whole.

[0083] The first free locking device 610 is provided with a plurality of
first slots 611 which are matched and articulated with the third
extensions 1014, 1024, 1034 or 1044 of the first, second, third and
fourth fixtures 101, 102, 103, and 104 of the side beam 300. The first
slots 611 are provided with structure which can interlock the third
extensions 1014, 1024, 1034 or 1044 of the first, second, third and
fourth fixtures 101, 102, 103, and 104 such that the first, second, third
and fourth fixtures 101, 102, 103, and 104 can be securely arranged
thereto. By this arrangement, the overall structure of the side beam 300
can be moved as a whole without worry about the falling off of the first,
second, third and fourth fixtures 101, 102, 103, and 104.

[0084] Referring to FIGS. 24 and 25, the second free locking device 620 is
securely interlocked to the second and fourth fixtures 102, 104 which are
located on the ends of the side beam 300. Accordingly, with the
corporation of the first free locking device 620, the first, second,
third and fourth fixtures 101, 102, 103, and 104 of both the side beams
300 on a common supporting plane can be moved together as a whole.

[0085] The second free locking device 620 is provided with a pair of
second slot 621 along the longitudinal direction. The second slots 621
are interlocked with the fourth extensions 1029, 1049 of the second and
fourth fixtures 101, 104 located on the sides of the side beam 300 on a
common supporting plane. The second free locking device 620 is further
defined with mounting hole 622. When the second slots 621 are meshed with
the fourth extensions 1029 or 1049, the mounting hole 622 are aligned
with the mounting holes 1030 or 1050 of the fourth extensions 1029 or
1049. As a result, with a bolt member (not shown thereof), the second
free locking device 620 can be readily interlocked with the second or
fourth fixtures 102 or 104.

[0086] By the provision of the above described configuration, the fixtures
on each supporting plane of the cartridge of the glass substrate can be
readily and individually installed and removed. Accordingly, any
supporting surface can be installed or removed according to field
requirements. In case a glass substrate was damaged or broken on a
certain of supporting surface, then the fixtures interlocked thereof can
be readily arranged such that the supporting surfaces above the
supporting surface in which the glass substrate was broken can be moved
to a carrier, and then a cleaning process can be taken on the damaged or
broken glass substrate. For example, the large sized broken piece can be
removed manually, while the debris or small sized pieces can be vacuumed.
Afterward, the glass substrate thereunder can be carefully handled so as
to avoid a second damage.

[0087] By the provision of the cartridge used for glass substrate, the
damaged or defective glass substrate can be readily removed with the
novel configurations of the fixtures implemented therein. Specially, no
second damages to those intact glass substrate during the handling of the
damaged or defective glass substrate.
